Subject: [PATCH 1/2] staging: slicoss: fix dma memory leak

Fix memory leak in slic_card_init. If the driver fails to poll for an
interrupt after requesting config data from the device the dma memory
is never freed.

This patch was originally sent here https://lkml.org/lkml/2014/5/6/7 with
my google.com email address. But due to Google's recent change in DMARC
policies, that patchset was silently dropped for at least some users
(including my personal gmail account). So I'm sending it out now with
my gmail.com account. Let me know if this is an issue. Thanks.
